Amongmultiple third signal lines SL3, as shown in FIG. 1B, the third signalline SL31, for example, electrically connects multiple fourth redsub-pixels R4 arranged in the first direction D1 in the second regionA2, and the third signal line SL32, for example, electrically connectsmultiple fourth green sub-pixels G4 arranged in the first direction D1in the second region A2, and the third signal line SL33, for example,electrically connects multiple fourth blue sub-pixels B4 arranged in thefirst direction D1 in the second region A2.

The display device 1 may further include a fourth signal line SL4 and afifth signal line SL5, and the number of the fourth signal line SL4 andthe fifth signal line SL5 in the display device 1 may be multiple.Multiple fourth signal lines SL4 are electrically connected to multiplesub-pixels arranged in the second direction D2. For example, multiplefourth signal lines SL4 and multiple fifth signal lines SL5 are, forexample, data lines, and multiple fourth signal lines SL4 (such as thefourth signal line SL41, the fourth signal line SL42, and the fourthsignal line SL43) can be arranged in the first region A1 (refer to theregion without background color in FIG. 1B) and the second region A2(refer to the region with dots that are arranged regularly and denselyin FIG. 1B). The multiple fifth signal lines SL5 can be arranged in thesecond region A2 without passing through the first region A1. In someembodiments, multiple fifth signal lines SL5 are not electricallyconnected to the first sub-pixel P1 in the first region A1.

In this embodiment, as shown in FIG. 1B, the first region A1 (refer tothe region without background color in FIG. 1B) is mainly composed oflarge-area sub-pixels, and the large-area sub-pixels may include thefirst sub-pixel P1. In some embodiments, a white sub-pixel W may also bearranged in the first region A1, and the white sub-pixel W may bearranged between two first pixel units U1 that are adjacent in the firstdirection D1. The second region A2 (refer to the region with dots thatare arranged regularly and densely in FIG. 1B) is mainly composed ofsmall-area sub-pixels, and the small-area sub-pixels may include thesecond sub-pixel P2, the third sub-pixel P3, and the fourth sub-pixelP4. The third region A3 (refer to the region with dots that are arrangedregularly and sparsely in FIG. 1B) is located between the first regionA1 and the second region A2. A width from the edge of the pixelelectrode (not shown) of the second sub-pixel P2 in the second region A2to the closest edge of the pixel electrode of the first sub-pixel P1 inthe first region A1 in the first direction D1 is the width W3 of thethird region A3. In some embodiments, the white sub-pixel W may belocated in the third region A3 other than the first region A1. Thedisplay device 1 may further include a shielding component 10. Theshielding component 10 can be arranged corresponding to the third regionA3. For example, the shielding component 10 may at least partiallyoverlap or completely overlap the third region A3 in the normaldirection DV, so as to shield the line located in the third region A3.The width W10 of the shielding component 10 in the first direction D1may be greater or less than the width W3 of the third region A3. In someembodiments, other than the third region A3, the shielding component 10can further shield the first signal line SL1 or other signal linesoutside the third region A3, such as shielding the first signal lineSL1, the second signal line SL2 and the fourth signal line SL4 locatedin the first region A1, and shielding the first signal line SL1 to thefourth signal line SL4 located in the second region A2. The shieldingcomponent 10 may include a black matrix or other light-shielding orlight-absorbing materials, but is not limited thereto. By arranging apart of the white sub-pixel W in the third region A3, it helps to reducethe area of circuit turning area S occupied in the area of the firstsub-pixel P1 in the first region A1 and/or the second sub-pixel P2 inthe second region A2, thereby helping to reduce the coverage area orwidth of the shielding component 10 in the region outside the thirdregion A3. In this manner, the aperture ratio or light transmittance ofthe sub-pixels (for example, the first sub-pixel P1 or the secondsub-pixel P2) in the region outside the third region A3 maintainsunchanged. In some embodiments, the width W3′ of the shielding component10 in the second region A2 in the first direction D1 may be less thanthe width W3 of the shielding component 10 in the third region A3 in thefirst direction D1.

For ease of reading, FIG. 1B shows the first signal line SL1 with thicksolid line, and shows the second signal line SL2, the third signal lineSL3, and the fourth signal line SL4 with thin solid line. However, itshould be understood that the line width of the first signal line SL1may be the same or different from the line width of any one of thesecond signal line SL2, the third signal line SL3, and the fourth signalline SL4. In addition, the wiring method of the first signal line SL1 tothe fourth signal line SL4 as well as the relative arrangementrelationship between them and multiple sub-pixels, or the area or shapeof each sub-pixel can be changed depending on requirements, and are notlimited to the illustration shown in FIG. 1B. For example, although notshown, multiple second signal lines SL2 may not extend into the firstregion A1, but electrically connect multiple third sub-pixels P3 in thesecond region A2 located opposite to the first region A1 from one sideof the first region A1 (for example, one side where the first region A1is connected to the second region A2 or one side where first region A1is not adjacent to the second region A2) or from multiple sides thatdetour the first region A1. In addition, although it is not shown, thesecond pixel unit U2 can also exchange positions with any third pixelunit U3 arranged in the second direction D2.
